The URLs you gave for the pictures didn't work for me, but it's probably the Sport, model 3320, which was part of Campy's low-end Gran Sport road group. According to Sutherland's Handbook, the bolt circle diameter for these is 116 mm, and the distance between the chainring bolts is 101 mm. Sutherland's lists several makes of cranks, include the TA Professional, that had the same bolt circle diameter.
